Abstract

Background and objectives: Different techniques of continuous renal replacement therapy (CRRT) might have different effects on calcium, phosphate and magnesium concentrations. Accordingly, we tested whether continuous veno-venous hemodiafiltration (CVVHDF) or continuous venovenous hemofiltration (CVVH) would achieve better control of these electrolytes. Design: Retrospective controlled study. Setting: Two tertiary Intensive Care Units. Patients: Critically ill patients with acute renal failure (ARF) treated with CVVHDF (n=49) or CVVH (n=50). Interventions: Retrieval of daily morning ionized calcium, phosphate and magnesium before and after the initiation of CRRT for up to 2 weeks of treatment. Measurements and results: Before treatment, both groups had a high incidence of abnormal ionized calcium concentrations (57.2% for CVVHDF vs 46.0% for CVVH; NS). After treatment, both groups showed a significant increase in serum calcium concentration over the first 48 h (p=0.041 vs p=0.0048) but hypercalcemia was more common during CVVHDF (15.3% vs 0.4%; p
